Multidimensional Array Merging

Multidimensional Array Merging - php

$result = $array[0];
for ($i = 1; $i < count($array); $i++) {
foreach ($result as $key => &$value) {
$value = array_merge($value, $array[$i][$key]);
}
}
Now $result should be an associative array that contains the merged contents of all the original sub-arrays.

You can cycle using an index and add the attribute of the second array to the first:
for ($index = 0; $index < count($array1); $index++) {
$array1[$index]->mysummary = $array2[$index]->mysummary;
}

foreach ($array1 as $key => $value) {
$array1[$key]->mysummary = $array2[$key]->mysummary;
}
echo '<pre>';print_r($array1);

You can use a combination of array_map and array_merge to achieve the same without any dependency of a static key of arrays.
$result = array_map(function($a,$b){
return array_merge(isset($a) ? $a : array(), isset($b) ? $b : array());
},$a1,$a2);
Demo.

PHP - Looping through indexed JSON array

You can use loop in $result["response"] as:
$json = '{"success":true,"error":null,"response":[{"id":"59c30487db6be86b7f8b465a","loc":{"long":-90.45,"lat":43.43},"report":{"code":"R","type":"heavy rain","name":"Gillingham","detail":{"text":1,"rainIN":1,"rainMM":25.4},"reporter":"co-op observer","comments":"","timestamp":1505952240,"cat":"rain","dateTimeISO":"2017-09-20T19:04:00-05:00","datetime":"2017-09-20T19:04:00-05:00","wfo":"arx"},"place":{"name":"gillingham","state":"wi","county":"richland","country":"us"},"profile":{"tz":"America\/Chicago"}},{"id":"59c302a9db6be82a758b46e8","loc":{"long":-90.93,"lat":43.32},"report":{"code":"R","type":"heavy rain","name":"Mount Sterling","detail":{"text":2.25,"rainIN":2.25,"rainMM":57.15},"reporter":"trained spotter","comments":"","timestamp":1505951760,"cat":"rain","dateTimeISO":"2017-09-20T18:56:00-05:00","datetime":"2017-09-20T18:56:00-05:00","wfo":"arx"},"place":{"name":"mount sterling","state":"wi","county":"crawford","country":"us"},"profile":{"tz":"America\/Chicago"}},{"id":"59c30106db6be8146c8b4661","loc":{"long":-89.53,"lat":44.45},"report":{"code":"R","type":"heavy rain","name":"Plover","detail":{"text":1.05,"rainIN":1.05,"rainMM":26.67},"reporter":"co-op observer","comments":"One hour total rainfall. also measured a 49 mph wind gust at 511 pm. no hail.","timestamp":1505950800,"cat":"rain","dateTimeISO":"2017-09-20T18:40:00-05:00","datetime":"2017-09-20T18:40:00-05:00","wfo":"grb"},"place":{"name":"plover","state":"wi","county":"portage","country":"us"},"profile":{"tz":"America\/Chicago"}},{"id":"59c3080adb6be8d5138b4654","loc":{"long":-89.33,"lat":44.37},"report":{"code":"H","type":"hail","name":"4 mi NNW Blaine","detail":{"text":0.88,"hailIN":0.88,"hailMM":22.35},"reporter":"trained spotter","comments":"Nickel size hail and heavy rain. 3.25 to 3.49 inches in the past 2 hours.","timestamp":1505950680,"cat":"hail","dateTimeISO":"2017-09-20T18:38:00-05:00","datetime":"2017-09-20T18:38:00-05:00","wfo":"grb"},"place":{"name":"blaine","state":"wi","county":"portage","country":"us"},"profile":{"tz":"America\/Chicago"}},{"id":"59c30106db6be8146c8b4660","loc":{"long":-90.93,"lat":43.32},"report":{"code":"H","type":"hail","name":"Mount Sterling","detail":{"text":0.75,"hailIN":0.75,"hailMM":19.05},"reporter":"trained spotter","comments":"Hail ranged from 1\/2 to 3\/4 inch.","timestamp":1505950200,"cat":"hail","dateTimeISO":"2017-09-20T18:30:00-05:00","datetime":"2017-09-20T18:30:00-05:00","wfo":"arx"},"place":{"name":"mount sterling","state":"wi","county":"crawford","country":"us"},"profile":{"tz":"America\/Chicago"}},{"id":"59c2fd80db6be844598b466d","loc":{"long":-89.77,"lat":44.21},"report":{"code":"R","type":"heavy rain","name":"6 mi ESE New Rome","detail":{"text":4,"rainIN":4,"rainMM":101.6},"reporter":"trained spotter","comments":"","timestamp":1505949840,"cat":"rain","dateTimeISO":"2017-09-20T18:24:00-05:00","datetime":"2017-09-20T18:24:00-05:00","wfo":"arx"},"place":{"name":"rome","state":"wi","county":"adams","country":"us"},"profile":{"tz":"America\/Chicago"}},{"id":"59c2f678db6be898338b4673","loc":{"long":-89.3,"lat":44.46},"report":{"code":"H","type":"hail","name":"Amherst Junction","detail":{"text":1,"hailIN":1,"hailMM":25.4},"reporter":"trained spotter","comments":"","timestamp":1505948340,"cat":"hail","dateTimeISO":"2017-09-20T17:59:00-05:00","datetime":"2017-09-20T17:59:00-05:00","wfo":"grb"},"place":{"name":"amherst junction","state":"wi","county":"portage","country":"us"},"profile":{"tz":"America\/Chicago"}},{"id":"59c2f2f6db6be8a2208b4672","loc":{"long":-89.4,"lat":44.26},"report":{"code":"H","type":"hail","name":"Almond","detail":{"text":2,"hailIN":2,"hailMM":50.8},"reporter":"trained spotter","comments":"Report via social media","timestamp":1505948160,"cat":"hail","dateTimeISO":"2017-09-20T17:56:00-05:00","datetime":"2017-09-20T17:56:00-05:00","wfo":"grb"},"place":{"name":"almond","state":"wi","county":"portage","country":"us"},"profile":{"tz":"America\/Chicago"}}]}';

Looping in a complex array

You can access this data by filtering the array.
In PHP >= 5.5.0 you can make a search like this;
$key = array_search('John Doe', array_column($yourArray, 'cardholdersname'));
This method will return the array that matched given criteria.

How to combine multidimensional arrays?

for($index=0; $index<=4; $index++){
$final_array[$index] = array_merge($product[$index],$pricing[$index]);
}
This would give you the desired array.

Try
foreach ($products as $key => $product){
$products[$key] = array_merge($product, $prices[$key])
}

array_unique wrongly discarding values

I'm trying to use array_unique to discard of repeated values.

every time I use array_unique($results) only the first value is returned

Where am I going with array_unique?

You can't use array_unique with nested arrays. The comparison used is clearly documented:
(string) $elem1 === (string) $elem2
